Biological Pathways Screensaver
The Biological Pathways screensaver shows the top-level pathways of human biology from Reactome, ranked by how many distinct molecular entities take part — a rough measure of how much of the cell's machinery each one involves. It's free, runs in your browser, and ESC exits.
How the Biological Pathways screensaver works
The background pipeline reads this from the Reactome API and saves a snapshot the saver loads.

It refreshes on a schedule, so what you see stays current.
Colours can be changed in settings; nothing is stored beyond your own browser.

Frequently asked questions
- Is this real data?
- Yes — it comes from the Reactome API and is refreshed on a schedule.
- Why is this fetched by the pipeline?
- The lightweight top-pathways endpoint carries no entity counts. Only the full events hierarchy does, and it is several megabytes — fine for a daily server job, too heavy to pull in every browser.
- Is a key needed?
- No. This source is fully key-less.
- Is it free?
- Yes — free, no download, in your browser.
